I'm going to be quite blunt here.
This draft comes nowhere close to displaying the competency at English required to write for this site. It's a confusing mess, and I come out of two rounds with it not knowing what it even does (and, without a spot of exaggeration, a fresh headache). It's a book of some kind, and but that's about all I can tell you.
If English isn't your first language, I'd either put in a lot more study into its grammar and mechanics before we even look at the creative side, or find a creative writing pursuit in your native language.
And if English is your first language, I'd say seriously pay attention in English class. Valuable stuff they teach in there.

To get this out in the open, what you have are two anomalies tied to the book. The first is a nebulous incident of "bad luck" to those who know about it. The end result of the "bad luck" is similar to Dr. Gerald's Driving Skills.

This is not a good thing. Not only is that overpowered, but it is clearly a transparent effort to make the book more dangerous.

Second anomaly is a matter displacement field that seems to cause objects to dissapear from between one day to five months, before bringing them back as a humanoid "monster of the week".

This is also not a good thing. While it hits #4 on The Big List of Overdone SCP Cliches, the real issue is the fact that it simply makes Things What Kill You. Death is a cheap thrill on this site, and we're all essentially jaded by it. The fact that the monthly D-class terminations are falling out of headcanon favor not because of the ethical concerns and human rights violations, but because it is unfeasable due to the limited supply should speak volumes about how the community tends to view fictional portrayals of death.

As for formatting and other stuff; the Foundation doesn't use "bases" but "Site-XX" and "Area-XX", the "[ ]" are uneccessary EXCEPT when adding [REDACTED] or [DATA EXPUNGED ], it's "personnel" and not "Personal", and finally, Thamuiel is when a SCP is considered vital to the Foundation's goals of containment, and "Neutralized" is when a SCP is no longer anomalous or when it is destroyed. There is no way your SCP would have ever been considered Thamuiel, and there was no reason given for the "Neutralized" class.
